White Valley of Slaughter - What Questions should Uncover

We've started creating our dungeon, White Valley of Slaughter , from random generators, but now you need to answer questions about it.

Questions like..

Is the valley a mountain valley or some sort of ravine?

Why is the wraith there and why does it seek release?

Who is the Hero buried in the tomb

What to Discover

This post was originally just going to be answering the questions, until I got side-tracked about what I wanted from answering the questions.

We want things that are useful in our adventure, so we want our questions to uncover the following

History. You want background and depth to your adventure, but only so much as to be useful for the players or to create a sense of life in the adventure.

Plot Hooks. Players that are engaged in the adventure are going to remember it and show more interest than not. You can look for loose ends that could easily be tied to the PCs, such as a treasure one of them is hunting for, an NPC they know or a place they have a historic tie to.

Allies, Hindrances and Shopkeepers. Also NPCs by another name, these are characters that can supply help, knowledge or difficulties to the PCs.

Adversaries and Challenges. Monsters & Traps in D&D, these are creatures or entities who want to stop the PCs. These could be combat encounters,

Mysteries. Things for the players to uncover if they are curious, things that aren't immediately obvious. The identity of the mayor's secret lover, who is behind the curse on the village or the location of the secret chamber in the graveyard.

Rewards. Tied to the above, but ways to give bonuses to the PCs. The most obvious is treasure, but there are also loyal allies, pieces of land, cult membership, favour of the gods and anything else that is normally of limited supply.
